This app is simply the best shy of proxies that block ads on all apps which requires wifi and you don't know if a proxy will spy on your activity in all apps. This app is well worth the buy and I rarely buy an app. Everything you need is built on and the owner is very polite and always responds and responds quickly. If you want a certain rule you can create a hide or block and emailing the owner helps here. He can step you through the process or even create it for you and email it to you and you can open the attachment in the app and BAM there it is. I'm so glad I bought this app! :)
